The surface electrode 102 and the driving electrode 103 are both circular.
The piezoelectric substrate 101 is made of piezoelectric ceramics.

Because the ultrasonic atomization sheet 1 has good atomization effect, the ultrasonic atomization sheet 1 with smaller size can achieve larger smoke quantity effect, and the ultrasonic atomization sheet 1 has smaller size, thereby being beneficial to the miniaturization development of products using the ultrasonic atomization sheet 1.
When the surface electrode 102 and the driving electrode 103 are electrified, the oscillating section 106 is driven by the potential change to perform high-frequency oscillation, and the oscillation amplitude of the oscillating section 106 is maximum, so that the tobacco tar or other smoke-generating substances contacted on the surface of the oscillating section 106 are atomized to generate smoke.
